| Popis: | Bladder cancer (BC) is one of the most common tumors in the urinary system. Noncoding RNAs are considered to take part in cellular phenotypes and are emerging as diagnostic and prognostic biomarkers of BC. The aim of this study is to investigate the clinical significance of neuroblastoma- associated transcript 1 (NBAT1) gene and its effects on malignant cellular phenotypes in BC. NBAT1 gene was low-expressed in BC tissues and cell lines and its low-expression was related with high pathological grade and metastasis of BC. Upregulation of NBAT1 gene depressed cell viability and invasiveness of KK47 and T24 cells and arrested KK47 and T24 cells at G1 stage. In addition, NBAT1 could target silence the expression of miR-21-5p in RNA-induced silencing complex-dependent manner. KK47 and T24 cells with miR-21-5p knockdown showed reduced cell viability, G1-stage arrest, and depressed invasiveness. MiR-21-5p mediates the regulatory effects of NBAT1 on malignant cellular phenotypes of BC cells. Moreover, SOCS6 gene was a target gene of miR-21-5p, and miR-21-5p modulated malignant cellular phenotypes of KK47 and T24 cells through targeted silencing of SOCS6. In conclusion, low-expression of NBAT1 is associated with the progress and metastasis of BC, and NBAT1 inhibits malignant cellular phenotypes through miR-21-5p/SOCS6 axis in BC. Our findings help to elucidate the tumorigenesis of BC, and future study will provide a novel therapeutic target for BC. |
